How do you log to Firebug from an extension?

Question

I'm writing an extension for Firefox, and I need to log some data to Firebug's console. Within the scope of my addon, "console" is undefined, and "window.content.console" is also undefined. So how do I log to the console?

Answer 1

Since you're not writing Javascript that executes within a window, console is not defined.

So you need to reference the Firebug extension first:

Firebug.Console.log(str);

Answer 2

To log to the console from inside a firefox extension’s javascript:

Application.console.log("Hello from my Firefox Extension!");
